Macro can be
tricky — Depth of Field drops significantly, and decreasing the aperture to
increase DOF results in slow shutter speeds. This might allow movement, either
of the camera or of the subject, to ruin your photo. Using a flash to super-illuminate
your subject, so you can use that small aperture and still have a fast shutter,
often means that the background drops into darkness, looking very unnatural.
So then you're trying two flashes, and now your setup is heavy, bulky
and awkward. You get the idea.

In this case, I was working
with natural light, since flash would have destroyed the background and shadows
and changed the appearance of the dew. I used a tripod (carefully, couldn't
disturb the leaf!), and got straight on with the leaf, to keep as much of it
the same distance from the lens and in focus (you can see the stem is out before
it even joins the plant). Set my aperture and used Depth-Of-Field Preview to
check it, and triggered the camera remotely with Mirror Lock-Up active to reduce
vibrations as much as possible. And let's not forget waiting for the breeze
to die down.
